I wrote two small apps: one binds a PUB socket to an endpoint and sends N messages to it; the other connects a SUB socket to that same endpoint and receives N messages. The sender optionally can wait a certain amount of ms between each send, and it always waits for 60 seconds at the end. I am attaching both files; all my tests are under Windows XP.
I run the following commands on two separate windows: # send 20 msgs, waiting 50 ms between them, no poll ./sender tcp://127.0.0.1:5009 20 50 0 # receive 20 messages ./receiver tcp://127.0.0.1:5009 20 This works erratically. Sometimes receiver receives less than 20 messages; sometimes it receives NONE. Is it the case that PUB/SUB sockets are unreliable? This is sort of a surprise to me... If they are not, what could explain this behavior?
